To provide a thermal power generation system including an auxiliary steam system that collects solar heat to generate steam and uses the steam as an auxiliary steam for the thermal power plant in order to suppress the decrease of output or efficiency of a steam turbine.
The thermal power generating plant includes: a primary boiler 1 for generating the steam by burning a fossil fuel; a steam turbine driven by the steam generated by the boiler 1; a steam condenser 5 for condensing the steam that drives the steam turbine; a water supply system for supplying the condensed water discharged from the steam condenser 5 to the primary boiler 1; a steam turbine facility having an auxiliary device that is driven by the steam extracted from the steam turbine; and a solar heat concentrator for heating a heat medium using the solar heat. An auxiliary steam is generated by heating some supplied water extracted from the water supply system using the solar heat concentrator and the auxiliary steam is supplied to the auxiliary device as steam used for driving.
